The answer spans from weeks to years, depending on scale — and most people drastically underestimate the pre-production phase.
A typical feature film (90-120 minutes) breaks down like this:
Pre-Production: 3-12 months
- Script development — 2-6 months (writing, rewrites, financing approval)
- Planning — 1-3 months (storyboarding, location scouting, budget finalization, hiring crew)
- Casting — 1-2 months (auditions, negotiations)
Production (Principal Photography): 4-12 weeks
- Most films shoot 5-10 weeks. A big-budget action film might take 4-6 months. An indie drama on weekends might stretch to 9 months part-time.
- Pace: typically 2-4 pages of script per day (a page ≈ 1 minute of screen time).
Post-Production: 4-12 months
- Editing — 2-4 months (assembling footage, pacing, visual cuts)
- Visual effects — 2-8 months (if needed; VFX-heavy films take the longest)
- Color grading, sound design, music — 1-3 months
- Final reviews and adjustments — 1-2 months
Timeline by Project Type
- Indie short film (5-15 min) — 1-6 months total (shoot in 3-5 days, edit in 2-4 weeks)
- YouTube video / web series episode — 1-4 weeks (shoot in 1-2 days, edit in 1-2 weeks)
- Feature film (typical) — 18-24 months
- Big-budget blockbuster — 2-4 years (Avatar: 4 years of principal photography + effects alone)
- Documentary — 6 months to 3+ years (highly variable depending on access and complexity)
The real surprise: editing and post-production take as long or longer than actually filming. A 10-week shoot generates 200+ hours of raw footage. Sorting, organizing, and refining that into 100 minutes takes months. VFX is the time killer — a single action sequence with CGI can take weeks.
Pro tip: The pre-production phase is where most first-time filmmakers stumble. Rushing it leads to confused crews, location conflicts, and reshoots (which cost time and money). A well-planned 3-month pre-production saves 2-3 weeks of shooting time.
